The Claw Rifle/Shotgun Sling adjusts quickly for length and can be used on any long arm equipped with sling swivel studs. It is made of a combination of synthetic materials that are durable, long lasting, and odor resistant. The sling webbing allows approximately 0.5" of stretch for comfort. The comfortable shoulder pad remains flexible to minus 40 degrees and is UV stabilized. Unlike other slings, The Claw won't slide around on your shoulder. It is all grip, no slip. The included Hush Stalker II swivels are rust free and will not rattle or squeak.
